Abstract
The demographic characteristics and genetic polymorphism data of 56 Chinese nationalities or 31 administrative divisions in Chinese mainland have repeatedly been the genetic research hotspots While most genetic studies focused on some particular Chinese populations based on autosomal or Ychromosomal genetic markers the forensic characteristics and phylogenetic analyses of the seventh largest Chinese population Yi ethnicity on the Xchromosomal genetic markers are scarce Here allele frequencies and forensic statistical parameters for 19 Xchromosomal short tandem repeat loci DXS7424DXS101 DXS6789DXS6809 DXS7423DXS10134 DXS10103HPRTBDXS10101 DXS10159DXS10162DXS10164 DXS10148DXS10135DXS8378 and DXS7132DXS10079DXS10074DXS10075 of 331 Chinese Yi individuals were obtained All 19 Xchromosomal short tandem repeat STR loci in females were consistent with the HardyWeinberg equilibrium test A total of 214 alleles were identified with the corresponding allele frequencies spanned from 00019 to 06106 The combined PE PDF and PDM were 09999999214 09999999999999999999993 and 09999999999998 respectively The high combined MECKrüger MECKishida MECDesmarais and MECDesmarais Duo were achieved as 09999999617638 09999999999971 09999999999971 and 09999999931538 respectively The findings suggested that the panel of 19 XSTR loci is highly polymorphic and informative in the Yi ethnic population and can be considered to be a powerful tool in forensic complex kinship identification Population differentiation analyses among 12 populations indicated that significant differences in genetic structure were observed in between the Yi ethnicity and the Chinese Uyghur as well as Kazakh and genetic homogeneity existed in similar ethnoorigin or geographic origin populations
